SPARK-ARRESTER.

SFECIFICATION forming part of Letters Patent No. 342,556, dated May 25, 1886.

Application filed January 29, 1886. Serial No. 190,251. (No model.)

To all whom, it may concern:

Be it known that I, JOHN COLUMBUS AL- BREOHT, of Columbus, in the county of Muscogee and State of Georgia, have invented a new and Improved Spark-Arrester, of which the following is a full, clear, and exact de scription.

My invention relates to the spark-arrester for which Letters Patent No. 295,322, dated March 18, 1884,were granted to me.

The object of my present invention is to provide a new and improved spark-arrester which separates the cinders from the smoke more effectively than those used heretofore, and which forces said cinders back into the firebox for consumption, and at the same time increases the draft of the fire by means of a hotblast from the smoke-stack, by which the cinders are carried back to the firebox.

My invention consists of a cone which arrests and deflects the sparks, and of .a device for facilitating the separation of the sparks from the smoke and carrying them more rapidly to the fire-box.

The invention also consists in various parts and details of construction and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of a smokestack provided with my improvement. Fig. 2 is a transverse section of the same. Fig. 3 is a sectional plan view on the line :0 m, Fig. 1. Fig. 4 is a side elevation, partly in section, of inyimproved cone. Fig. 5is asectional plan view on the line y y, Fig. 1. Fig. 6 is a side elevation of the ring. Fig. 7 is a plan view of the saddle. Fig. 8 is a sectional side elevation of the same 011 the line 2 2, Fig. 7.

The saddle A is attached to the boiler of the locomotive in any suitable manner, and supports the smoke-stack B, provided on top with the cap C. The saddle A is provided with the side passages, A, having slanting bottoms A,which open into the spark-fines I, leading to the fire-box of the boiler. These spark-fines may be either inside or outside of the boiler, as may be preferred.

The draft-pipeD extends from the top of the saddle A to the platform F, attached to the H and with an equalnumber of horizontal radial passages, I), each one of thelatter being placed between two of the former. The cap E of the cone E is formed on its under side into an inverted cone, 0.

The platform F is provided with a number of slanting openings, d, extending downward in a spiral direction, like the threads of a screw. Two of the openings a in the cone E, placed opposite each other on each side of the central longitudinal linejof the boiler,open into spouts or funnels F, provided with downwardly-extending pipes F, terminating in the passages A of the saddle A.

The spark-drum G is provided with perforations of any convenient size and shape, which perforations may be covered with caps or hoods of any suitable form at their lower and upper ends. r

The spark-drum G is supported at its lower end by the ring H, attached to the flaring shellB of the smoke-stack, and its upper end is attached to a ring-flange secured to the lower surface of the platform F in such a manner as to form the space G between the shell B and the drum G, and the space G between the drum G and the draft-pipeD.

The ring H is provided with the radial tubes H, leading to the draft-pipe D, the opening in the latter being protected by shields D, and 'with ridges H, placed midway between the openings of the tubes H and slanting downward toward the same.

The operation is as follows: The sparks and cinders driven by the force of the draft and exhaust are forced through the pipe D up to and against the lower surfaee'cf the inverted cone 0 of the cap E of the cone E, and are deflected and guided down through the openings a into the spark-drum G, and thence are driven back through the passages A of the saddle A, and through the spark-fiues I into the fire-box of the boiler. The smoke and the smoke and ases are driven by the exhaust upward against the' under-surface of the inverted cone, and thence downward through the passages a into the drum G and through the perforations in the wall of said drum G into the space ;G, from whichlthey pass up ward through the spiral open'in'gsd i also the space K, surrounding the cone E, and from there through the sleeve 0' of thccap into the air. Thus the passage of the sparks from the mouth of the draft-pipe into the spark-drum G is obviously more direct, and-"hence easier,; than through the cone described in my former patent, and the drum G'is relieved from ex- '1 5 cessive pressure within it, which may be caused by the passage of the exhaust into it; thusenabling the engine to make steam more freely, and-also to effect the separation of suoh'smoke as has "been forcdd into the drnm fiom the zo sparks whioh have come-with it through the 1 passages a by allowing the delivery *of this smoke through theiperforations ofthe drum G intd the space G'g whence it "mayesoapenpward, as before described. The 'motion of 2 5 P the spa'rks "whileflscendihg into the fl ues *I has been *beforedescribed. 'The sparks which have collected in the space G Hare "not allowed Y to accumulate i there, so' as to render it necessaryfito draw them *ofl by on tward -spark-spouts, hat *they "aredriven 'throughthe a; Hfiand their correspond- 1 'iug draftpipeopen ingsinto thed raft-pipeyand are then thrown upward again and against l the lower surface of i the 00116,"!18 at first.
